A test method is applied to an elevator system having a control unit and at least one bus node. The bus node has a first microprocessor and a second microprocessor and the control unit and the bus node communicate by a bus. Furthermore, the first microprocessor and the second microprocessor are connected without interruption by a signal line. The test method includes the steps: a specification signal is transmitted by the control unit to the first microprocessor, the first microprocessor transmits the signal to the second microprocessor, and the second microprocessor provides the signal for the control unit. Finally, the control unit verifies whether the provided signal corresponds to a signal expected by the control unit. The elevator system includes a monitoring device for carrying out the test method. |
